 interesting work to set upon. 



My eye trouble entirely prevents me from carry-

 this to me is most provoking, as they have been 

 yielding very interesting results ; and having now

 from any kind of intellectual work, and as in any 

 case I could not finish the second instalment of my 

 work upon ' Darwin and After Darwin ' by means of

 to Man, as far, at all events, as I have been able to 

 examine. Now I want to see whether hair-follicles, 

 or vestiges thereof, can be found in the terminal pha- 

 langes of any species of the order. So I am making 

 a number of sections of the skin of the backs of 

 the terminal phalanges of fingers and toes, of man
